The Woodward PGA-EG Governor/Actuator is designed specifically for marine applications requiring electronic engine control with mechanical backup. It combines the proven PG hydro-mechanical governor with electronic actuator flexibility, providing pneumatic tracking of the speed setting for complete backup speed control from a remote location with only a slight speed change on electronic signal loss.
Key Features
Electronic Control
- Electronic actuator accepts 0–200 mA control signal
- Compatible with all Woodward electronic controls
- Output range: 16 to 678 N·m (12 to 500 lb-ft) for all marine engine sizes
- Least-fuel-selection feature ensures smooth electronic-to-mechanical transfer
- Available in direct-acting (minimum fuel on signal loss) or reverse-acting
Mechanical Backup
- PGA hydro-mechanical ballhead backup governor
- Pneumatic speed tracking provides complete remote backup
- Only slight speed change on electronic signal loss — no gross overspeed or shutdown
- Proven PG governor dependability
- Redundant speed control for critical marine needs
Applications
- Marine propulsion with electronic control and mechanical backup
- Critical marine engine applications requiring redundant speed control
- All sizes of marine engines (16–678 N·m output)
- Retrofit of existing PG-governed marine engines to electronic control
